Walker was left out of Gordon Strachan’s two squads of 19 that will face the Czech Republic and Denmark later this month.

The Turkish centre-back saw some of the players on Strachan’s list and reckons Walker is better than most of those selected.

The midfielder showed his talent again with a dominant display against Dundee that he topped off by netting the only goal of the game in 52 minutes to send his side 17 points clear of Ross County in third spot.

The 22 year-old latched on to Arnaud Djoum’s threaded pass to round Dundee No.1 Scott Bain – a player who was called up for Scotland in midweek – to coolly stroke home his fourth goal in six league games since he returned to the team in February following knee surgery.

And Ozturk is adamant it is only a matter of time before the former Scotland Under-21 cap gains full international honours.

He said: “Jamie is a really good player. He was injured but has come back and scored four goals in his last seven games.

“Jamie is doing really well and he is a key man for Hearts. You can see his talent and he knows what he is doing.

“I am sure he will be called up by Scotland soon. Maybe the recent Scotland squads came too soon for him after his injury to be selected.

“I have seen some of the names who are in there and I think he is better than them.

“I see him very day at training and I am impressed. At 22 Jamie is still young and he is going to be a big name.”

This was another huge win for Robbie Neilson’s men as they reeled off their fourth successive Premiership victory on the spin.

The fact Neilson’s well-drilled side also haven’t conceded a goal in any of those fixtures is testament to the hard work put in on the training ground.

Hearts are a tough nut to crack under Neilson and while they trail second-placed Aberdeen by nine points the Tynecastle side still have a game in hand.

Ozturk, like his manager, believes it is still possible for Hearts to overhaul the Reds in the run-in.

He said: “I think we can catch Aberdeen because the gap is only nine points and we have a game in hand and we also have still to play them twice. We will just try to win all of our games and see where that takes us.”

With Igor Rossi and Callum Paterson missing from the Jambos defensive line-up this win was all the more impressive.

Ozturk, at 23, was the senior pro at the back as he organised a rearguard made up of three teenagers – Jordan McGhee, John Souttar and Liam Smith – to claim another clean sheet.

In truth Hearts could have been out of sight in the first half in this one as Walker missed a sitter after just 15 seconds when he dragged an effort wide when clean through on Bain. Juanma then smashed in a 10-yard bullet header that brought out a superb reflex save from Bain.

McGhee had the ball in the net only for it to be ruled out for offside before Djoum passed up a gilt-edged chance when he somehow side-footed wide of the target from close range.

However, it was Dundee who were then left cursing their luck when Neil Alexander saved from Greg Stewart and Nick Ross before Paul McGowan slammed one wide and Cameron Kerr crashed one over the top.

Sub Rory Loy should have cancelled out Walker’s goal when he ran clear in 81 minutes but he could only hammer an effort off Alexander’s legs.

Smith hooked the bouncing ball clear off the line and with that the Dark Blues’ chance of grabbing a point had gone.

Ozturk though praised Hearts’ fighting spirit and their ability to grind out wins. He said: “When you look at the first half we missed four great chances so we could have killed the game then.

“We didn’t do that and we didn’t play as well in the second half. But it was an important win and another clean sheet.

“The other three members of our back four were all 19 so I felt like the grandpa!

“They did well and that’s four clean sheets in a row now.

“With Igor and out everyone was asking how the young guys would cope so I am really happy for them.

“It’s nice for defenders to keep clean sheets. We create a lot of chances and score in almost every game so if we can keep the other team out we know we will win.”
